Solution:

The correct option is (2).
The tight junction can be defined as a complex of multi proteins at the junction which plays an important role in preventing leakage of the solutes being transported along with water between the cells and helps in sealing the pathway of cellular apparatus. They are found only in vertebrates. 

Adhering junctions are present at the cell-cell junction found in epithelial and endothelial tissues. Its cytoplasmic side is connected with the actin cytoskeleton. They play an important role by allowing the blastocyst to penetrate the uterine epithelial cells.

A gap junction is also called nexus or macula communicans which is mainly found in nerve cells of the body. They play an important role in directly connecting the cytoplasm of the two cells. Thus, allow various kinds of molecules, and electrical impulses to pass with help of a regulated gate in the cells.

Synaptic junctions pass information from one cell to another through neurotransmitters.
